Answer:
The other angle is 190-7x.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Let A be the third angle.
A + (3x-20) + (4x+10) = 180
A = 180 - (3x - 20) - (4x + 10) = 190 - 7x
Answer:
∠ 2 = 104°
Step-by-step explanation:
Since the trees are parallel, then
∠ 2 and 76° are same- side interior angles and are supplementary, thus
∠ 2 + 76° = 180° ( subtract 76° from both sides )
∠ 2 = 104°
Answer:
I believe it is a=64; b=2 divided by 10 (I'm sorry if it's wrong I hope you pass)
Answer: 300
We know that 5×3=15. Since we are trying to get 1500 we Multiply 300×5 and get 1500.
<u>How do we know?</u>
- As you can see if you cross out 2 of the 0 in 300 you have 3×5. When you multiply it you get 15.
- Also if you cross out 1 of the 0 in 300 you have 30×5. When you multiply that you get 150.
As you see when you still multiply either of those problems you have 15 in it. So we should know 300×5=1500.
Note: We can also multiply 500×3 and get 1500. You still get the same answer but just switched numbers.
Yes. Because blah blah blas blah blah blah
